To all whom it may concern: 1

Be it known that I, PATRICK J. BRENNAN, a citizen of the United States, residing at Tuxedo Park, in the county of Orange, State of New York, have invented certain new and useful Improvements in AslrSif-ters; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable othersskilled in the artto which it appertains to make and use the.

same.

The present invention is directed to improvements in ash Sifters, and particularly to that type which is used in connection with furnaces.

The invention has for its object to provide an ash sifter adapted to be arranged within the ash pit of the furnace and directly under the grate thereof so that when the grate is shaken the ashes and cinders fall through the grate bars and drop into the sifter.

A further object of the invention is to provide an ash sifter of this character which can be readily operated while in the ash pit so as to separate the dust from the larger particles.

A still further object of the invention is to provide a sifter of this character which can be rolled from the ash pit after the sifting operation so that the unconsumed coal can be again used in the furnace.

Still another object of the invention is to provide an ash sifter having sides which are folded so that when the sifter is within the ash pit the sides can be disposed in inclined position so as to occupy the entire transverse area of the ash pit so that the ashes from the grate will be directed into the sifter.

It is a well known fact that the ash pit door is of less width than the ash pit itself and the grate bars, therefore it is deemed necessary that the sides of the sifter be folded so that the sifter can be readily passed into and out of the ash pit door.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the sifter.

Fig. 2 is a longitudinal sectional view ash pit thereof.

Fig. 3. is a transverse sectional view.

through the same. y

. Referring to the. drawing 1 indicates the furnace which is provided with the usual grate bars 21 and ash pit?) and doorways.

The sifter 5 consists of sidebars 6* and end bars .7, said. side bars being formed from an, gle lron and have hingedly connected to their vertical webs the. lower ends of the sldes 18,

saidwsides having their ends provided with substantially triangular shaped plates 9, which are arranged at right angles to the sides and are adapted to overlap the ends 10, said ends being formed integral with the bars 7.

Having their ends connected to the bars 6 are bars 11, said bars being connected by a bar 12. Depending from the bars 11 are brackets 13, said brackets having carried thereby spindles 14 and upon which are rotatably mounted wheels 15, said wheel serving to permit the sifter to be easily rolled into and out of the ash pit. Removably sup ported on the side bars 6 and end bars 7 is a screen 16 which is adapted to receive the ashes which fall through the grate bars.

The plates 9 are provided with ar cuate slots 17 which, are engaged by the rivets 18 carried by the ends 10, said slots serving to limit the swinging movement of the sides 8, but permitting the same to be swung out-- wardly a suflicient distance to occupy the space under the grate. The plates 9 are pro vided with cars 19 which serve as hand holds so that the sides 8 can be readily swung outwardly or folded when it is desired to remove the sifter from the-ash pit, which is necessary since the width of the ash pit door is less than that of the ash pit.

A tray 20 may be used, as shown in Figs. 2 and 3 of the drawing so that the sifted ashes can be removed from the ash pit upon removal of the tray. It will be of course understood that the wheels 15 roll upon the tray, or if the tray, is not used the wheels travel on the floor of the ash pit.

A socket 21 is carried by the forward end 10 of the sifter for detachably receiving the lower end of the handle 22, said handle being of such shape that the same can be grasped by a person in a standing position so that the sifter can be reciprocated when desired.

What is claimed is An ash sifter comprising a frame including side and end members formed of angle iron, the vertical webs of the end members being of a greater height than those of the side members, sides hinged to the upper edge of the webs of the side members for movement to positions in Vertical alinement with the last named webs and also for movement outwardly to an oblique angle with respect to said webs, segmental plates carried by the ends of the sides and extending inwardly at right angles to the sides and in overlap ping relation to the end members of the frame, said plates having arcuate slots, stops carried by said end members and extending into the slots of the plates and engageable with the ends of said slots to limit the movements of the sides to their vertical and ob lique positions and prevent inward move- Gopies of this patent may be obtained for ment thereof with respect to said vertical Webs of the side members, a screen removably disposed upon the horizontal webs of the side and end members of the frame, spaced longitudinal and transverse bars secured to the frame beneath said screen, and supporting wheels carried by certain of said bars for movement of the sifter longitudinally upon the wheels.

In testimony whereof, I aflix my signature, in the presence of tWo witnesses.

. PATRICK JOSEPH BRENNAN.
